Answer:

$13.01d-2.65$

Step-by-step explanation:

We have been given an expression $3.26d+9.75d-2.65$ . We are asked to combine like terms to simplify our given expression.

To combine like terms, we need to add $3.26d$ to $9.75d$ as both these terms has variable d.

$(3.26+9.75)d-2.65$

$13.01d-2.65$

Therefore, simplified form of our given expression would be $13.01d-2.65$ .

The waiting time in line at an ice cream shop has a uniform distribution between 3 and 14 minutes. What is the 75th percentile o

lesya692 [45]

Answer:

The 75th percentile of this distribution is 11 .25 minutes.

Step-by-step explanation:

The random variable X is defined as the waiting time in line at an ice cream shop.

The random variable X follows a Uniform distribution with parameters a = 3 minutes and b = 14 minutes.

The probability density function of X is:

$f_{X}(x)=\frac{1}{b-a};\ a$

The pth percentile is a data value such that at least p% of the data-set is less than or equal to this data value and at least (100-p)% of the data-set are more than or equal to this data value.

Then the 75th percentile of this distribution is:

$P (X < x) = 0.75$

$\int\limits^{x}_{3} {\frac{1}{14-3}} \, dx=0.75\\\\ \frac{1}{11}\ \cdot\ \int\limits^{x}_{3} {1} \, dx=0.75\\\\\frac{x-3}{11}=0.75\\\\x-3=8.25\\\\x=11.25$

Thus, the 75th percentile of this distribution is 11 .25 minutes.

What is the definition of a four-dimensional (4-D) shape?

viktelen [127]

A four-dimensional space or 4D space is a mathematical extension of the concept of three-dimensional or 3D space. Three-dimensional space is the simplest possible generalization of the observation that only three numbers, called dimensions, are needed to describe the size or position of objects in the everyday world. For example, the volume of a rectangular box is found by measuring its length (usually labeled x), width (y), and depth (z).
